new light deadline! where can i get this

So we are progressing along upstairs, and the current phase is putting up new ceiling in the bedroom. However, before we do that, i want to install some new LED lights. I already have 2 LED disc lights wired to a switch.

my project is this: i want to install 2 more LED lights in the ceiling, but this time instead of a switch i want to be able to use a remote to turn them on and off. Where/ how can i do this?

basically something like a tv except the remote will be for controlling a set of lights.
thanks!

here is a pic of what is up now. the light is wired to a switch at the wall. if i connect the new LED remote lights to this light, i can still use the remote for the new lights right? since the IR or whatever is built into the light itself.

ok so here is my new idea:
i have an outlet in the room. i believe its hot. can i just splice into the outlet for my new lights?
in the case that i can do this, when i go to make the connections, am i allowed to put the 2 hot black wires on the same screw?( white goes to the other screw, and ground goes to green)
